Cladocera subfossils preserved in the modern and pre-1850 lake sediments of 23 lakes in the region were examined, as well as the Daphnia resting egg bank of Pocket Lake, a highly contaminated lake in which striking ecological changes were previously recorded.enAttribution-NonCommercial-ShareAlike 2.5 CanadaCladoceraPaleolimnologyYellowknife (Northwest Territories, Canada)Dataset
